Abstract
A lighting system is disclosed comprising an excitor which drives at least one reactor. The excitor is an electrical waveform generator that creates an AC waveform at a frequency between about 50 kHz and about 100 MHz. The reactor is an under-damped resonant circuit that includes a network of lighting elements. Reactive components are distributed among the lighting elements. These reactive components can regulate the current and voltage to individual lighting elements. The drive system is particularly useful for arrays of low-voltage lighting elements such as LEDs. It is fault tolerant in that the failure of individual elements need not affect the operation of remaining elements, and elements can be added and removed without affecting the serviceability of other elements.
